这种方法适用于简单的ASCII字符串,但处理多字节字符(如UTF-8编码的中文)时可能出现问题。 javascript function ab2str(arrayBuffer) { return String.fromCharCode.apply(null, new Uint8Array(arrayBuffer)); } const buffer = new ArrayBuffer(8); const uint8Array = new Uint8Array(buffer); uint8Array[0] ...
由于项目需要,需要从一个已知的ArrayBuffer中读取出字符串,虽然环境是typescript,但最终还是用的js的代码改了一下解决, publicUtf8ArrayToStr(array):string {varout,i,len,c;varchar2,char3; out=""; len=array.length; i= 0;while(i <len) { c= array[i++];switch(c >> 4) {case0:case1:case...

Convert ArrayBuffer/ArrayBufferView/Arraybufferto string with defined encoding. Available encoding:utf8,binary,base64,hex,ascii,latin1,ucs2,utf16andmany others. Note: in browser it relies onTextDecoder API, so if you are dealing with charsets other thanutf8,ascii,binaryorbase64in old browsers, ...

ArrayBuffer转为字符串,或者字符串转为ArrayBuffer,有⼀个前提,即字符串的编码⽅法是确定的。假定字符串采⽤UTF-16编码(JavaScript的内部编码⽅式),可以⾃⼰编写转换函数。// ArrayBuffer转为字符串,参数为ArrayBuffer对象 function ab2str(buf) { return String.fromCharCode.apply(null, new Uint16...
